Specification of Letters Patent.

Patented Sept. 23, 1919.

Application led March 22, 1918. Serial No. 224,021.

To all whom t may concern:

Be it known that I, PETER SGHNURR, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Rolling Screens, of which the following is a specification. The invention seeks to provide, as its principal object, a rolling fly screen carried on a spring actuated roller, the latter being designed for mounting on a Window frame on the outside of the latter' adjacent the meeting rails of the sash.

A further object of the invention is to provide unique tracks or guides for attachment to the window frame so that the side edges of `the screen may slidably engage therein. The two Guide members or tracks are connected togeilier at their upper ends by means lof transverse members between which the screen passes as it is being unrolled upon the roller.

A still further object of the invention is to provide a device of the kind set forth which is simple in construction, durable and effective in operation, and inexpensive to manufacture.

Other objects are in part obvious and in part hereinafter set forth.

To the exact embodiment in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the` demand, in so far' actual redu'ction ma as such changes or a terations are comprehended in Spirit by the annexed claim.

The same numerals of reference designate the same parts throughout the several figures ofthe drawings, wherein:`

Figure 1 is a view in elevation showing the application of the improved screen,

Fig. 2 is a similar elevational view, but looking at the opposite side from that shown in Fig. 1, l

Fig. 3 is a section on the line 3 3 of Fig. 1,

Fig. 4 is a perspective View of one of the roller supports,

Fig. 5 is a perspective view of the other of the roller supports,

Fi x6 is a plan view of the Wrench used for tightening the spring in the roller,

Fig. 7 is a detail sectional view showing lower end when it is drawn to a position for screening the window.

Referring to the drawings there is shown, a window frame A onfwhich the improved screen B is attached. This improved screen comprises the brackets 1 and 2, the spring actuating roller 3 which is similar to the conventional shade roller, the wire fabric 4 and guides 5 and 6. The bracket 1 is designed for 4attachment on the left hand vertical stile 7 of the frame A, while the bracket 2 is attached on the right hand stile 8, both being mounted at points slightly above the meeting rails 9 of the sash. Both these brackets support the spring actuated roller 3 whose round stud is pivotallymounted in the bracket l and Whose flattened stud is carried inthe recess 10 of the bracket 2. v.

The wire fabric 4 is secured to the roller 3 in any appropriate way, the fabricA being so cut that it is disclosed on the bias to permit its being freely rolled onto and ofi' of the roller 3. At the bottom edge, the fabric is appropriately secured to the longitudinal edge of a bar 11, which is L-shape in cross section, that flange to which' the fabric is attached being provided with a hand grip 12 which has an intermediate position with reference to the length of the bar. This hand grip 12 is intended to be on the outside of the window when the screen is mounted thereon. That flange of the bar 11 to which the fabric is attached is designed to stand vertical. Therefore, the remaining iiange of the bar lies horizon.;4 tally and being designed to project inwardly with reference to the window, it carries on its upper face, a hand grip 13, whereby the screen may be manipulated on the inside as well as on the outside when the hand grip 12 is employed.

In being raised and lowered, the side edges of the fabric move between the guides 5 and 6, a pair of which is attached to either of the stiles 7 or 8. i

On top of the sill lll of the window frame there rests a plate 15 having at either end, a flange 16, by means of whlch the plate is connected to both of the guides 5 at their bottom ends. This plate 15 is of a width ros substantially equal to the width of the lower be mounted on the sill 14C behind the plate, so that when the screen is in a lowered position, the horizontal flange of the rail 11 may rest on top of the springs, the plate closing the opening that would otherwise obtain below the bar 11 by the use of the springs.

A transversely disposed bar 19 connects the guides Sgnear their upper ends and a similarly disposed `bar 18 connects the guides 5 at their upper ends, the fabric 4 passing between these two transversely disposed bars when its side edges enter be'- -tween the guides.

To secure the screen in the lower position, there is provided an eye 20 which is attached to the sill 14 and this eye is adapted to be engaged by a hook 21 carried on the bottom face of the bar 11 and disposed medially with reference to the bar.

-Since the roller 3 is spring actuated, a wrench 22 is provided, which wrench has formed therein, a rectangular aperture 23, by means of which the wrench may be made to enga-gethe at stud of the roller to enable the spring to be tightened or loosened to give it the required twisting eort for rolling the spring thereupon.

lt will be observed that the screen and all its attendant parts are mounted on the window frame, so as to be conveniently placed to permit the upper sash to be raised or lowered without having it interfere with the screen. When the -upper sash is raised to its normal position, the upper edge of the transverse bar 19 is adjacent the lower bottom edge of the meeting rails 9 of the upper sash. rlhus the fabric f1 successfully screens the window when the lower sash 1s raised, since the fabric covers all the open space comprehended between the'sides of the Window frame and the transverse bars 1S and 19 and the transversely disposed plate 15.

From the foregoing description taken in conjunction with lthe accompanying drawings, the construction and use of the invention is thought to be suflicient to render versely disposed bar secured to the bottom edge of the fabric, guide members mounted on the vertical stiles of the frame and guiding the side edges of the fabric, the aforesaid transversely disposed bar being L-shaped in cross section so that one of its l flanges stands normally in a horizontal plane and the other in a vertical plane, a hand grip attached on each flange, transversely disposed bars connecting the upper ends Vof the guide members and disposed one on either side of the fabric, a transversely disposed plate connecting the two outside guide bars at their bottom ends, the

said plate having its lower edge resting upon the sill of the `Window frame, .spiral springs disposed upon the window sill behind the plate and in abutting relation to the horizontal flange of said L-shaped transversely disposed bar, and a fastener con# nected with the window sill and attacha'ble to said bar.
